ProMation Engineering, Inc. Linear Electric Actuator PL680

Designed and engineered for precision operation of linear process control valves. Up to 4400 lbs (19.57 kN) of force 2 inches (50mm) travel. Field Selectable Stops – Travel stops can be set by location with a mechanical switch or by a rated force switch, either on the down or up stroke. For example, the down stroke can be set with full force for consistent seating regardless of wear with the up stroke set by a mechanical switch to protect the stem plug connection. Proportional Control – Precision proportional control is achieved through a microcontroller based printed circuit board featuring 4-20mA, 1-5VDC, 0-10VDC or 2-10 VDC input and feedback as well as AutoCalibration or manual end of travel set point and alphanumeric diagnostic indicators. Manual Override – All ProMation Engineering linear actuators come with a standard manual override that allows fast and simple manual positioning.
